php_mapscript - showing polygon and point/annotation layers

[Mike Reilly]

Robert and list:

I think I've got this worked out. My original cgi-mapserver application used 
a hack to get both point and polygon data able to be filtered based on some 
extra data in their respective dbf files - namely site usage (USE1). As a 
result I had 3 layers with the same name as each other. While the cgi 
handled this fine, it appears that php is less forgiving. I started a .map 
file over again for my php application and have renamed the layers and 
everything seems to be much happier now.

Next major task on my list - create an interface to allow the creation of 
polygons to add to polygon shapefiles - whee!

Thanks again for your help.

Regards,
Mike
